Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	1. BASIS OF PRESENTATION General These unaudited Consolidated Financial Statements include the accounts of WSFS Financial Corporation (WSFS, and together with its subsidiaries, the Company), and its consolidated subsidiaries. WSFS’ primary subsidiary is Wilmington Savings Fund Society, FSB (WSFS Bank or the Bank). As of March 31, 2024, the other subsidiaries of WSFS include The Bryn Mawr Trust Company of Delaware (BMT-DE), Bryn Mawr Capital Management, LLC (BMCM), WSFS Wealth Management, LLC (Powdermill ® ), WSFS SPE Services, LLC, and 601 Perkasie, LLC. The Company also has three unconsolidated subsidiaries: WSFS Capital Trust III, Royal Bancshares Capital Trust I, and Royal Bancshares Capital Trust II . WSFS Bank has two wholly-owned subsidiaries: Beneficial Equipment Finance Corporation (BEFC) and 1832 Holdings, Inc. , and one majority-owned subsidiary, NewLane Finance Company (NewLane Finance ® ). Overview Founded in 1832, the Bank is one of the ten oldest bank and trust companies continuously operating under the same name in the United States (U.S.). The Company provides residential and commercial mortgage, commercial and consumer lending services, as well as consumer deposit and treasury management services. The Company's core banking business is commercial lending funded primarily by customer-generated deposits. In addition, the Company offers a variety of wealth management and trust services to individuals, institutions and corporations. The Federal Deposit Insurance Corporation (FDIC) insures the Company's customers’ deposits to their legal maximums. The Company serves its customers primarily from 114 offices located in Pennsylvania (57 ), Delaware ( 40) , New Jersey (14 ), Florida (1), Nevada (1) and Virginia (1) , its ATM network, website at www.wsfsbank.com and mobile app. Information on the website is not incorporated by reference into this Quarterly Report on Form 10-Q. The Company's leasing business is conducted by NewLane Finance ® . NewLane Finance ® originates small business leases and provides commercial financing to businesses nationwide, targeting various equipment categories including technology, software, office, medical, veterinary and other areas. In addition, NewLane Finance ® offers captive insurance through its subsidiary, Prime Protect. Basis of Presentation In preparing the unaudited Consolidated Financial Statements, the Company is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. Amounts subject to significant estimates include the allowance for credit losses (including loans and leases held for investment, investment securities available-for-sale and held-to-maturity), loans held for sale, lending-related commitments, goodwill, intangible assets, post-retirement benefit obligations, the fair value of financial instruments, and income taxes. Among other effects, changes to these estimates could result in future impairments of investment securities, goodwill and intangible assets, the establishment of additional allowance and lending-related commitment reserves, changes in the fair value of financial instruments, as well as increased post-retirement benefits and income tax expense. The Company's accounting and reporting policies conform to Generally Accepted Accounting Principles in the U.S. (GAAP), prevailing practices within the banking industry for interim financial information and Rule 10-01 of SEC Regulation S-X (Rule 10-01). Rule 10-01 does not require us to include all information and notes that would be required in audited financial statements. Operating results for the periods presented are not necessarily indicative of the results that may be expected for any future quarters or for the year ending December 31, 2024. These unaudited, interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and related notes included in the Annual Report on Form 10-K for the year ended December 31, 2023 (the 2023 Annual Report on Form 10-K) that was filed with the SEC on February 29, 2024 and is available at www.sec.gov or on the website at www.wsfsbank.com .

NONINTEREST INCOME	3. NONINTEREST INCOME Credit/debit card and ATM income The following table presents the components of credit/debit card and ATM income: Three Months Ended March 31, (Dollars in thousands) 2024 2023 Bailment fees $ 14,964 $ 8,684 Interchange fees 3,753 3,886 Other card and ATM fees 952 791 Total credit/debit card and ATM income $ 19,669 $ 13,361 Credit/debit card and ATM income is composed of bailment fees, interchange fees, and other card and ATM fees. Bailment fees are earned from bailment arrangements with customers. Bailment arrangements are legal relationships in which property is delivered to another party without a transfer of ownership. The party who transferred the property (the bailor) retains ownership interest of the property. In the event that the bailee files for bankruptcy protection, the property is not included in the bailee's assets. The bailee pays an agreed-upon fee for the use of the bailor's property in exchange for the bailor allowing use of the assets at the bailee's site. Bailment fees are earned from cash that is made available for customers' use at an offsite location, such as cash located in an ATM at a customer's place of business. These fees are typically indexed to a market interest rate. This revenue stream generates fee income through monthly billing for bailment services. Credit/debit card and ATM income also includes interchange fees. Interchange fees are paid by a merchant's bank to a bank that issued a debit or credit card used in a transaction to compensate the issuing bank for the value and benefit the merchant receives from accepting electronic payments. These revenue streams generate fee income at the time a transaction occurs and are recorded as revenue at the time of the transaction.

Trust fees are based on revenue earned from custody, escrow, trustee and trustee related services on structured finance transactions; indenture trustee, administrative agent and collateral agent services to individuals, institutions and corporations; commercial domicile and independent director services; and investment and trustee services to families and individuals. Most fees are flat fees, except for a portion of personal and corporate trustee fees where the Company earns a percentage on the assets under management or assets held within a trust. This revenue stream primarily generates fee income through monthly, quarterly and annual billings for services provided. Wealth management and advisory fees consists of fees from Bryn Mawr Trust (excluding BMT-DE), BMCM, Powdermill ® , and WSFS Wealth ® Investments. Wealth management and advisory fees are based on revenue earned from services including asset management, financial planning, family office, and brokerage.

As of March 31, 2024, the Company’s available-for-sale investment securities consisted of 973 securities, 965 of which were in an unrealized loss position. As of March 31, 2024, substantially all of the Corporation’s available-for-sale investment securities were mortgage-backed securities or collateral mortgage obligations which were issued or guaranteed by U.S. government-sponsored entities and agencies. As of March 31, 2024 and December 31, 2023, there were no holdings of securities of any one issuer, other than the U.S. government and its agencies, in an amount greater than 10% of shareholders’ equity. The scheduled maturities of held-to-maturity debt securities at March 31, 2024 and December 31, 2023 are presented in the table below: Held-to-Maturity Amortized Fair (Dollars in thousands) Cost Value March 31, 2024 (1) Within one year $ — $ — After one year but within five years 11,930 11,741 After five years but within ten years 47,195 46,747 After ten years 990,690 891,239 $ 1,049,815 $ 949,727 December 31, 2023 (1) Within one year $ — $ — After one year but within five years 10,932 10,856 After five years but within ten years 46,489 46,246 After ten years 1,001,144 928,829 $ 1,058,565 $ 985,931 (1) Actual maturities could differ from contractual maturities. MBS may have expected maturities that differ from their contractual maturities. These differences arise because issuers may have the right to call securities and borrowers may have the right to prepay obligations with or without prepayment penalty. The estimated weighted average duration of MBS was 5.8 years at March 31, 2024. The held-to-maturity debt securities are not collateral-dependent securities as these are general obligation bonds issued by cities, states, counties, or other local and foreign governments. Investment securities with fair market values aggregating $3.0 billion and $3.3 billion were pledged as collateral for investment sweep repurchase agreements, municipal deposits, and other obligations as of March 31, 2024 and December 31, 2023, respectively.

The unrealized losses are the result of changes in market interest rates subsequent to purchase, not credit loss, as these are highly rated agency securities with no expected credit loss, in the event of a default. As a result, there is no allowance for credit losses recorded for available-for-sale debt securities as of March 31, 2024.

Credit Quality Indicators Below is a description of each of the risk ratings for all commercial loans: • Pass . These borrowers currently show no indication of deterioration or potential problems and their loans are considered fully collectible. • Special Mention. These borrowers have potential weaknesses that deserve management’s close attention. Borrowers in this category may be experiencing adverse operating trends, for example, declining revenues or margins, high leverage, tight liquidity, or increasing inventory without increasing sales. These adverse trends can have a potential negative effect on the borrower’s repayment capacity. These assets are not adversely classified and do not expose the Bank to significant risk that would warrant a more severe rating. Borrowers in this category may also be experiencing significant management problems, pending litigation, or other structural credit weaknesses. • Substandard or Lower . These borrowers have well-defined weaknesses that require extensive oversight by management. Borrowers in this category may exhibit one or more of the following: inadequate debt service coverage, unprofitable operations, insufficient liquidity, high leverage, and weak or inadequate capitalization. Relationships in this category are not adequately protected by the sound financial worth and paying capacity of the obligor or the collateral pledged on the loan, if any. A distinct possibility exists that the Bank will sustain some loss if the deficiencies are not corrected. In addition, some borrowers in this category could have the added characteristic that the possibility of loss is extremely high. Current circumstances in the credit relationship make collection or liquidation in full highly questionable. Such impending events include: perfecting liens on additional collateral, obtaining collateral valuations, an acquisition or liquidation preceding, proposed merger, or refinancing plan. Residential and Consumer Loans The residential and consumer loan portfolios are monitored on an ongoing basis using delinquency information and loan type as credit quality indicators. These credit quality indicators are assessed in the aggregate in these relatively homogeneous portfolios. Loans that are greater than 90 days past due are generally considered nonperforming and placed on nonaccrual status. The following tables provide an analysis of loans by portfolio segment based on the credit quality indicators used to determine the allowance for credit losses as of March 31, 2024.

Troubled Loans The Company offers loan modifications to commercial and consumer borrowers that may result in a payment delay, interest rate reduction, term extension, principal forgiveness, or combination thereof. Loan modifications are offered on a case-by-case basis and are generally term extension, payment delay, and interest rate reduction modification types. Forbearance (due to hardship) programs result in modification types including payment delay and/or term extension. In addition, certain reorganization bankruptcy judgments may result in interest rate reduction, term extension, or principal forgiveness modification types. The following tables show the period-end amortized cost basis of troubled loans modified during the three months ended March 31, 2024 and 2023, disaggregated by portfolio segment and type of modification granted: Three Months Ended March 31, 2024 (Dollars in thousands) Term Extension More-Than-Insignificant Payment Delay Combination- Term Extension and Payment Delay Combination- Term Extension and Interest Rate Reduction Combination - Payment Delay and Interest Rate Reduction Total % of Total Loan Category Commercial and industrial $ 31,865 $ 349 $ 820 $ — $ — $ 33,034 1.27 % Construction 1,910 — — — — 1,910 0.18 % Consumer (1) 325 702 1,932 — — 2,959 0.14 % Total $ 34,100 $ 1,051 $ 2,752 $ — $ — $ 37,903 0.29 % (1) Includes home equity lines of credit, installment loans, unsecured lines of credit and education loans.

(2) Represents the weighted-average decrease in the contractual interest rate on the modified loans. (3) Represents the percentage of loans deferred over the total loan portfolio excluding reverse mortgages at fair value. As of March 31, 2024 and December 31, 2023, the Company had commitments to extend credit of $19.2 million and $18.4 million, respectively, to borrowers experiencing financial difficulty whose terms had been modified. Upon the Company’s determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is written off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount. The following table shows the amortized cost of loans that received a term extension modification that had a payment default during the three months ended March 31, 2024 and were modified in the 12 months before default to borrowers experiencing financial difficulty. There were no loans that had a payment default during the three months ended March 31, 2023 and were modified in the 12 months before default to borrowers experiencing financial difficulty.

Leases [Abstract]
LEASES	8. LEASES As a lessee, the Company enters into leases for its bank branches, corporate offices, and certain equipment. As a lessor, the Company primarily provides financing through its equipment leasing business. Lessee The Company's ongoing leases have remaining lease terms of less than one year to 21 years, which includes renewal options that are exercised at its discretion. The Company's lease terms to calculate the lease liability and right-of-use asset include options to extend the lease when it is reasonably certain that the Company will exercise the option. The lease liability and right-of-use asset is included in Other liabilities and Other assets , respectively, in the unaudited Consolidated Statements of Financial Condition. Leases with an initial term of 12 months or less are not recorded on the unaudited Consolidated Statements of Financial Condition. Lease expense is recognized on a straight-line basis over the lease term. Operating lease expense is included in Occupancy expense in the unaudited Consolidated Statements of Income.

Fair Value Disclosures [Abstract]
FAIR VALUE DISCLOSURES OF FINANCIAL ASSETS AND LIABILITIES	12. FAIR VALUE DISCLOSURES OF FINANCIAL ASSETS AND LIABILITIES FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES ASC 820-10, Fair Value Measurement (ASC 820-10) defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820-10 establishes a fair value hierarchy that prioritizes the use of inputs used in valuation methodologies into the following three levels: • Level 1: Inputs to the valuation methodology are quoted prices, unadjusted, for identical assets or liabilities in active markets. A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available. • Level 2: Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets; inputs to the valuation methodology include quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs to the valuation methodology that are derived principally from or can be corroborated by observable market data by correlation or other means. • Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Level 3 assets and liabilities include financial instruments whose value is determined using discounted cash flow methodologies, as well as instruments for which the determination of fair value requires significant management judgment or estimation. The following tables present financial instruments carried at fair value as of March 31, 2024 and December 31, 2023 by level in the valuation hierarchy (as described above): March 31, 2024 (Dollars in thousands) Quoted Significant Significant Total Fair Assets measured at fair value on a recurring basis: Available-for-sale securities: CMO $ — $ 451,891 $ — $ 451,891 FNMA MBS — 2,947,349 — 2,947,349 FHLMC MBS — 111,751 — 111,751 GNMA MBS — 43,940 — 43,940 GSE agency notes — 179,298 — 179,298 Other assets — 168,510 44 168,554 Total assets measured at fair value on a recurring basis $ — $ 3,902,739 $ 44 $ 3,902,783 Liabilities measured at fair value on a recurring basis: Other liabilities $ — $ 156,243 $ 13,426 $ 169,669 Assets measured at fair value on a nonrecurring basis: Other investments $ — $ — $ 14,714 $ 14,714 Other real estate owned — — 1,210 1,210 Loans held for sale — 26,858 — 26,858 Total assets measured at fair value on a nonrecurring basis $ — $ 26,858 $ 15,924 $ 42,782 December 31, 2023 (Dollars in thousands) Quoted Significant Significant Total Fair Assets measured at fair value on a recurring basis: Available-for-sale securities: CMO $ — $ 464,619 $ — $ 464,619 FNMA MBS — 3,042,350 — 3,042,350 FHLMC MBS — 115,532 — 115,532 GNMA MBS — 43,340 — 43,340 GSE agency notes — 180,696 — 180,696 Other assets — 153,569 78 153,647 Total assets measured at fair value on a recurring basis $ — $ 4,000,106 $ 78 $ 4,000,184 Liabilities measured at fair value on a recurring basis: Other liabilities $ — $ 137,616 $ 14,026 $ 151,642 Assets measured at fair value on a nonrecurring basis Other investments $ — $ — $ 15,206 $ 15,206 Other real estate owned — — 1,569 1,569 Loans held for sale — 29,268 — 29,268 Total assets measured at fair value on a nonrecurring basis $ — $ 29,268 $ 16,775 $ 46,043 Fair value is based on quoted market prices, where available. If such quoted market prices are not available, fair value is based on internally developed models or obtained from third parties that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include unobservable parameters. The Company's valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While the Company believes its valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Available-for-sale securities Securities classified as available-for-sale are reported at fair value using Level 2 inputs. The Company believes that this Level 2 designation is appropriate under ASC 820-10, as these securities are GSEs and GNMA securities with almost all fixed income securities, none are exchange traded, and all are priced by correlation to observed market data. For these securities the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, U.S. government and agency yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the security’s terms and conditions, among other factors. Other investments Other investments includes equity investments without readily determinable fair values, which are categorized as Level 3. The Company’s equity investments without readily determinable fair values are held at cost, and are adjusted for any observable price changes in orderly transactions for the identical or a similar investment of the same issuer during the reporting period and its equity method investments are initially recorded at cost based on the Company’s percentage ownership in the investee, and are adjusted to reflect the recognition of the Company’s proportionate share of income or loss of the investee based on the investee’s earnings. Other real estate owned Other real estate owned consists of loan collateral which has been repossessed through foreclosure or other measures. Initially, foreclosed assets are recorded at the fair value of the collateral less estimated selling costs. Subsequent to foreclosure, valuations are updated periodically and the assets may be marked down further, reflecting a new cost basis. The fair value of other real estate owned was estimated using Level 3 inputs based on appraisals obtained from third parties. Loans held for sale The fair value of loans held for sale is based on estimates using Level 2 inputs. These inputs are based on pricing information obtained from wholesale mortgage banks and brokers and applied to loans with similar interest rates and maturities. Other assets Other assets include the fair value of interest rate products, derivatives on the residential mortgage held for sale loan pipeline, and risk participation agreements. Valuation of interest rate products is obtained from an independent pricing service and also from the derivative counterparty. Valuation of the derivative related to the residential mortgage held for sale loan pipeline is based on valuation of the loans held for sale portfolio as described above in Loans held for sale . Valuation of risk participation agreements are obtained from an independent pricing service. Other liabilities Other liabilities include the fair value of interest rate products, derivatives on the residential mortgage held for sale loan pipeline, foreign exchange forward contracts, risk participation agreements, and derivative related to the sale of certain Visa Class B common shares. Valuation of interest rate products is obtained from an independent pricing service and also from the derivative counterparty. Valuation of the derivative related to the residential mortgage held for sale loan pipeline is based on valuation of the loans held for sale portfolio as described above in Loans held for sale. Valuation of foreign exchange forward contracts and risk participation agreements are obtained from an independent pricing service. Valuation of the derivative related to the sale of certain Visa Class B common shares is based on: (i) the agreed upon graduated fee structure; (ii) the length of time until the resolution of the Visa covered litigation; and (iii) the estimated impact of dilution in the conversion ratio of Class B shares resulting from changes in the Visa covered litigation. FAIR VALUE OF FINANCIAL INSTRUMENTS The reported fair values of financial instruments are based on a variety of factors. In certain cases, fair values represent quoted market prices for identical or comparable instruments. In other cases, fair values have been estimated based on assumptions regarding the amount and timing of estimated future cash flows that are discounted to reflect current market rates and varying degrees of risk. Accordingly, the fair values may not represent actual values of the financial instruments that could have been realized as of period-end or that will be realized in the future. The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: Cash, cash equivalents, and restricted cash For cash and short-term investment securities, including due from banks, federal funds sold or purchased under agreements to resell and interest-bearing deposits with other banks, the carrying amount is a reasonable estimate of fair value. Investment securities Investment securities include debt securities classified as held-to-maturity or available-for-sale. Fair value is estimated using quoted prices for similar securities, which the Company obtains from a third party vendor. The Company uses one of the largest providers of securities pricing to the industry and management periodically assesses the inputs used by this vendor to price the various types of securities owned by the Company to validate the vendor’s methodology as described above in available-for-sale securities. Other investments Other investments includes equity investments without readily determinable fair values (see discussion in “Fair Value of Financial Assets and Liabilities” section above) as well as equity method investments. Loans held for sale Loans held for sale are carried at their fair value (see discussion in “Fair Value of Financial Assets and Liabilities” section above). Loans and leases Loans and leases are segregated by portfolio segments with similar financial characteristics. The fair values of loans and leases, with the exception of reverse mortgages, are estimated by discounting expected cash flows using the current rates at which similar loans would be made to borrowers with comparable credit ratings and for similar remaining maturities. The fair values of reverse mortgages are based on the net present value of the expected cash flows using a discount rate specific to the reverse mortgages portfolio. The fair value of nonperforming loans is based on recent external appraisals of the underlying collateral, if the loan is collateral dependent. Estimated cash flows, discounted using a rate commensurate with current rates and the risk associated with the estimated cash flows, are used if appraisals are not available. This technique does contemplate an exit price. Stock in the Federal Home Loan Bank (FHLB) of Pittsburgh The fair value of FHLB stock is assumed to be equal to its cost basis, since the stock is non-marketable but redeemable at its par value. Accrued interest receivable The carrying amounts of interest receivable approximate fair value. Other assets Other assets include the fair value of interest rate products, derivatives on the residential mortgage held for sale loan pipeline, and risk participation agreements (see discussion in “Fair Value of Financial Assets and Liabilities” section above). Deposits The fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, money market and interest-bearing demand deposits, is assumed to be equal to the amount payable on demand. The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using rates currently offered for deposits with comparable remaining maturities. Borrowed funds Rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate the fair value of existing debt. Off-balance sheet instruments The fair value of off-balance sheet instruments, including swap guarantees of $6.9 million at March 31, 2024 and $7.3 million at December 31, 2023, respectively, and standby letters of credit, approximates the recorded net deferred fee amounts. Because letters of credit are generally not assignable by either the Company or the borrower, they only have value to the Company and the borrower. In determining the fair value of the swap guarantees, the Company assesses the underlying credit risk exposure for each borrower in a paying position to the third-party financial institution. Accrued interest payable The carrying amounts of interest payable approximate fair value.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	13. DERIVATIVE FINANCIAL INSTRUMENTS Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both economic conditions and its business operations. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities. The Company manages a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions. The Company does not use derivative financial instruments for trading purposes. Fair Values of Derivative Instruments The table below presents the fair value of derivative financial instruments as well as their location on the unaudited Consolidated Statements of Financial Condition as of March 31, 2024.

To accomplish this objective, the Company primarily uses interest rate options, including floors, caps, collars, or swaps as part of its interest rate risk management strategy. Interest rate options designated as cash flow hedges involve the receipt of fixed amounts from a counterparty in exchange for the Company making variable-rate payments over the life of the agreements without exchange of the underlying notional amount. The Company has agreements with certain derivative counterparties that contain a provision under which, if it defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. The Company also has agreements with certain derivative counterparties that contain a provision where if it fails to maintain its status as a well-capitalized or adequately capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. As of March 31, 2024, the Company had 13 interest rate floors purchased at an aggregate premium of $19.7 million with an aggregate notional amount of $1.0 billion to hedge variable cash flows associated with a variable rate loan pool through the first quarter of 2027. Changes to the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income (loss) and is subsequently reclassified into earnings in the period that the hedged forecast transaction affects earnings. If the Company determines that a cash flow hedge is no longer highly effective, future changes in the fair value of the hedging instrument would be reported in earnings. As of March 31, 2024, the Company determined the cash flow hedges remain highly effective. During the three months ended March 31, 2024, $0.8 million of amortization expense on the premium was reclassified into interest income compared to less than $0.1 million during the three months ended March 31, 2023. The Company does not expect any unrealized gains or losses related to cash flow hedges to be reclassified into earnings in the next twelve months. Derivatives Not Designated as Hedging Instruments: Customer Derivatives – Interest Rate Swaps The Company enters into interest rate swaps with commercial loan customers wishing to manage interest rate risk. The Company then enters into corresponding swap agreements with swap dealer counterparties to economically hedge the exposure arising from these contracts. The interest rate swaps with both the customers and third parties are not designated as hedges under ASC 815, Derivatives and Hedging (ASC 815) and are marked to market through earnings. As the interest rate swaps are structured to offset each other, changes to the underlying benchmark interest rates considered in the valuation of these instruments do not result in an impact to earnings; however, there may be fair value adjustments related to credit quality variations between counterparties, which may impact earnings as required by ASC 820. As of March 31, 2024, there were no fair value adjustments related to credit quality. Derivative Financial Instruments from Mortgage Banking Activities Derivative financial instruments related to mortgage banking activities are recorded at fair value and are not designated as accounting hedges. This includes commitments to originate certain fixed-rate residential mortgage loans to customers, also referred to as interest rate lock commitments. The Company may also enter into forward sale commitments to sell loans to investors at a fixed price at a future date and trade asset-backed securities to mitigate interest rate risk. Foreign Exchange Forward Contracts The Company enters into foreign exchange forward contracts (FX forwards) with customers to exchange one currency for another on an agreed date in the future at an agreed exchange rate. The Corporation then enters into corresponding FX forwards with swap dealer counterparties to economically hedge its exposure on the exchange rate component of the customer agreements. The FX forwards with both the customers and third parties are not designated as hedges under ASC 815 and are marked to market through earnings. Exposure to gains and losses on these contracts increase or decrease over their respective lives as currency exchange and interest rates fluctuate. As the FX forwards are structured to offset each other, changes to the underlying term structure of currency exchange rates considered in the valuation of these instruments do not result in an impact to earnings; however, there may be fair value adjustments related to credit quality variations between counterparties, which may impact earnings as required by ASC 820. As of March 31, 2024, there were no fair value adjustments related to credit quality. Risk Participation Agreements The Company may enter into a risk participation agreement (RPA) with another institution as a means to assume a portion of the credit risk associated with a loan structure which includes a derivative instrument, in exchange for fee income commensurate with the risk assumed. This type of derivative is referred to as an “RPA sold.” In addition, in an effort to reduce the credit risk associated with an interest rate swap agreement with a borrower for whom the Corporation has provided a loan structured with a derivative, the Corporation may purchase an RPA from an institution participating in the facility in exchange for a fee commensurate with the risk shared. This type of derivative is referred to as an “RPA purchased.” Swap Guarantees The Company entered into agreements with one unrelated financial institution whereby that financial institution entered into interest rate derivative contracts (interest rate swap transactions) directly with customers referred to them by the Company. Under the terms of the agreements, the financial institution has recourse to us for any exposure created under each swap transaction, only in the event that the customer defaults on the swap agreement and the agreement is in a paying position to the third-party financial institution. This is a customary arrangement that allows us to provide access to interest rate swap transactions for our customers without creating the swap ourselves. These swap guarantees are accounted for as credit derivatives. At March 31, 2024 and December 31, 2023, there were 185 and 188 variable-rate to fixed-rate swap transactions between the third-party financial institutions and the Company's customers, respectively. The initial notional aggregate amount was approximately $0.7 billion at March 31, 2024 and December 31, 2023. At March 31, 2024, the swap transactions remaining maturities ranged from under 1 year to 11 years. At March 31, 2024, none of these customer swaps were in a paying position to third parties, with our swap guarantees having a fair value of $6.9 million. At December 31, 2023, none of these customer swaps were in a paying position to third parties, with the Company's swap guarantees having a fair value of $7.3 million. However, for both periods, none of the Company's customers were in default of the swap agreements. Credit-risk-related Contingent Features The Company has agreements with certain derivative counterparties that contain a provision under which, if it defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. The Company has minimum collateral posting thresholds with certain of its derivative counterparties, and has posted collateral of $2.5 million in cash against its obligations under these agreements which meets or exceeds the minimum collateral posting requirements. If the Company had breached any of these provisions at March 31, 2024, it could have been required to settle its obligations under the agreements at the termination value.

Segment Reporting [Abstract]
SEGMENT INFORMATION	14. SEGMENT INFORMATION As defined in ASC 280, Segment Reporting (ASC 280), an operating segment is a component of an enterprise that engages in business activities from which it may earn revenues and incur expenses, whose operating results are regularly reviewed by the enterprise’s chief operating decision makers to make decisions about resources to be allocated to the segment and assess its performance, and for which discrete financial information is available. The Company evaluates performance based on pretax net income relative to resources used, and allocate resources based on these results. The accounting policies applicable to the Company's segments are those that apply to its preparation of the accompanying unaudited Consolidated Financial Statements. Based on these criteria, the Company has identified three segments: WSFS Bank, Cash Connect ® , and Wealth Management.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	15. COMMITMENTS AND CONTINGENCIES Secondary Market Loan Sales The Company typically sells newly originated residential mortgage loans in the secondary market to mortgage loan aggregators and to GSEs such as FHLMC, FNMA, and on a more limited basis, the FHLB. Loans held for sale are reflected on the unaudited Consolidated Statements of Financial Condition at fair value with changes in the value reflected in the unaudited Consolidated Statements of Income. Gains and losses are recognized at the time of sale. The Company periodically retains the servicing rights on residential mortgage loans sold which results in monthly service fee income. The mortgage servicing rights are included in Goodwill and intangible assets on the unaudited Consolidated Statements of Financial Condition. Otherwise, the Company sells loans with servicing released on a nonrecourse basis. Rate-locked loan commitments that the Company intends to sell in the secondary market are accounted for as derivatives under ASC 815. The Company does not sell loans with recourse, except for standard loan sale contract provisions covering violations of representations and warranties and, under certain circumstances, early payment default by the borrower. These are customary repurchase provisions in the secondary market for residential mortgage loan sales. These provisions may include either an indemnification from loss or the repurchase of the loans. Repurchases and losses have been rare and no provision is made for losses at the time of sale. There was one repurchase during the three months ended March 31, 2024 for $0.3 million and no repurchases during the same period in 2023. Unfunded Lending Commitments At March 31, 2024 and December 31, 2023, the allowance for credit losses of unfunded lending commitments was $11.8 million and $12.1 million, respectively. A provision release of $0.3 million was recognized during the three months ended March 31, 2024 compared to a provision release of $0.2 million during the three months ended March 31, 2023.

LEGAL AND OTHER PROCEEDINGS In accordance with the current accounting standards for loss contingencies, the Company establishes reserves for litigation-related matters that arise in the ordinary course of its business activities when it is probable that a loss associated with a claim or proceeding has been incurred and the amount of the loss can be reasonably estimated. Litigation claims and proceedings of all types are subject to many uncertain factors that generally cannot be predicted with assurance. In addition, the Company's defense of litigation claims may result in legal fees, which it expenses as incurred. There were no material changes or additions to other significant pending legal or other proceedings involving the Company other than those arising out of routine operations.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Mar. 31, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation In preparing the unaudited Consolidated Financial Statements, the Company is required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. Amounts subject to significant estimates include the allowance for credit losses (including loans and leases held for investment, investment securities available-for-sale and held-to-maturity), loans held for sale, lending-related commitments, goodwill, intangible assets, post-retirement benefit obligations, the fair value of financial instruments, and income taxes. Among other effects, changes to these estimates could result in future impairments of investment securities, goodwill and intangible assets, the establishment of additional allowance and lending-related commitment reserves, changes in the fair value of financial instruments, as well as increased post-retirement benefits and income tax expense. The Company's accounting and reporting policies conform to Generally Accepted Accounting Principles in the U.S. (GAAP), prevailing practices within the banking industry for interim financial information and Rule 10-01 of SEC Regulation S-X (Rule 10-01). Rule 10-01 does not require us to include all information and notes that would be required in audited financial statements. Operating results for the periods presented are not necessarily indicative of the results that may be expected for any future quarters or for the year ending December 31, 2024. These unaudited, interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and related notes included in the Annual Report on Form 10-K for the year ended December 31, 2023 (the 2023 Annual Report on Form 10-K) that was filed with the SEC on February 29, 2024 and is available at www.sec.gov or on the website at www.wsfsbank.com . All significant intercompany accounts and transactions were eliminated in consolidation.
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS The following accounting pronouncements were adopted by the Company during the three months ended March 31, 2024, but did not have a material impact on the unaudited Consolidated Financial Statements. • ASU No. 2023-01, Leases (Topic 842) — Common Control Agreements • ASU No. 2023-02, Investments — Equity Method and Joint Ventures (Topic 323) Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method There were no other applicable material accounting pronouncements adopted by the Company since December 31, 2023. Accounting Guidance Pending Adoption as of March 31, 2024 ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures: In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures . The amendments are intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. Adoption is required retrospectively for all prior periods presented in the financial statements. The Company is currently evaluating this update to determine the impact on the Company’s disclosures. ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures: In March 2023, The FASB issued ASU 2023-02, Investments—Equity Method and Joint Ventures (Topic 323) Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method . The amendments permit reporting entities to elect to account for any equity investments in a tax credit program using the proportional amortization method if certain conditions are met. The amendments are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. Adoption is required on a prospective, modified retrospective, or retrospective basis depending on the amendment. The Company is currently evaluating this update to determine the impact on the Company’s disclosures.
Fair Value Measurement	Available-for-sale securities Securities classified as available-for-sale are reported at fair value using Level 2 inputs. The Company believes that this Level 2 designation is appropriate under ASC 820-10, as these securities are GSEs and GNMA securities with almost all fixed income securities, none are exchange traded, and all are priced by correlation to observed market data. For these securities the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, U.S. government and agency yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the security’s terms and conditions, among other factors. Other investments Other investments includes equity investments without readily determinable fair values, which are categorized as Level 3. The Company’s equity investments without readily determinable fair values are held at cost, and are adjusted for any observable price changes in orderly transactions for the identical or a similar investment of the same issuer during the reporting period and its equity method investments are initially recorded at cost based on the Company’s percentage ownership in the investee, and are adjusted to reflect the recognition of the Company’s proportionate share of income or loss of the investee based on the investee’s earnings. Other real estate owned Other real estate owned consists of loan collateral which has been repossessed through foreclosure or other measures. Initially, foreclosed assets are recorded at the fair value of the collateral less estimated selling costs. Subsequent to foreclosure, valuations are updated periodically and the assets may be marked down further, reflecting a new cost basis. The fair value of other real estate owned was estimated using Level 3 inputs based on appraisals obtained from third parties. Loans held for sale The fair value of loans held for sale is based on estimates using Level 2 inputs. These inputs are based on pricing information obtained from wholesale mortgage banks and brokers and applied to loans with similar interest rates and maturities. Other assets Other assets include the fair value of interest rate products, derivatives on the residential mortgage held for sale loan pipeline, and risk participation agreements. Valuation of interest rate products is obtained from an independent pricing service and also from the derivative counterparty. Valuation of the derivative related to the residential mortgage held for sale loan pipeline is based on valuation of the loans held for sale portfolio as described above in Loans held for sale . Valuation of risk participation agreements are obtained from an independent pricing service. Other liabilities Other liabilities include the fair value of interest rate products, derivatives on the residential mortgage held for sale loan pipeline, foreign exchange forward contracts, risk participation agreements, and derivative related to the sale of certain Visa Class B common shares. Valuation of interest rate products is obtained from an independent pricing service and also from the derivative counterparty. Valuation of the derivative related to the residential mortgage held for sale loan pipeline is based on valuation of the loans held for sale portfolio as described above in Loans held for sale. Valuation of foreign exchange forward contracts and risk participation agreements are obtained from an independent pricing service. Valuation of the derivative related to the sale of certain Visa Class B common shares is based on: (i) the agreed upon graduated fee structure; (ii) the length of time until the resolution of the Visa covered litigation; and (iii) the estimated impact of dilution in the conversion ratio of Class B shares resulting from changes in the Visa covered litigation. FAIR VALUE OF FINANCIAL INSTRUMENTS The reported fair values of financial instruments are based on a variety of factors. In certain cases, fair values represent quoted market prices for identical or comparable instruments. In other cases, fair values have been estimated based on assumptions regarding the amount and timing of estimated future cash flows that are discounted to reflect current market rates and varying degrees of risk. Accordingly, the fair values may not represent actual values of the financial instruments that could have been realized as of period-end or that will be realized in the future. The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: Cash, cash equivalents, and restricted cash For cash and short-term investment securities, including due from banks, federal funds sold or purchased under agreements to resell and interest-bearing deposits with other banks, the carrying amount is a reasonable estimate of fair value. Investment securities Investment securities include debt securities classified as held-to-maturity or available-for-sale. Fair value is estimated using quoted prices for similar securities, which the Company obtains from a third party vendor. The Company uses one of the largest providers of securities pricing to the industry and management periodically assesses the inputs used by this vendor to price the various types of securities owned by the Company to validate the vendor’s methodology as described above in available-for-sale securities. Other investments Other investments includes equity investments without readily determinable fair values (see discussion in “Fair Value of Financial Assets and Liabilities” section above) as well as equity method investments. Loans held for sale Loans held for sale are carried at their fair value (see discussion in “Fair Value of Financial Assets and Liabilities” section above). Loans and leases Loans and leases are segregated by portfolio segments with similar financial characteristics. The fair values of loans and leases, with the exception of reverse mortgages, are estimated by discounting expected cash flows using the current rates at which similar loans would be made to borrowers with comparable credit ratings and for similar remaining maturities. The fair values of reverse mortgages are based on the net present value of the expected cash flows using a discount rate specific to the reverse mortgages portfolio. The fair value of nonperforming loans is based on recent external appraisals of the underlying collateral, if the loan is collateral dependent. Estimated cash flows, discounted using a rate commensurate with current rates and the risk associated with the estimated cash flows, are used if appraisals are not available. This technique does contemplate an exit price. Stock in the Federal Home Loan Bank (FHLB) of Pittsburgh The fair value of FHLB stock is assumed to be equal to its cost basis, since the stock is non-marketable but redeemable at its par value. Accrued interest receivable The carrying amounts of interest receivable approximate fair value. Other assets Other assets include the fair value of interest rate products, derivatives on the residential mortgage held for sale loan pipeline, and risk participation agreements (see discussion in “Fair Value of Financial Assets and Liabilities” section above). Deposits The fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, money market and interest-bearing demand deposits, is assumed to be equal to the amount payable on demand. The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using rates currently offered for deposits with comparable remaining maturities. Borrowed funds Rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate the fair value of existing debt. Off-balance sheet instruments The fair value of off-balance sheet instruments, including swap guarantees of $6.9 million at March 31, 2024 and $7.3 million at December 31, 2023, respectively, and standby letters of credit, approximates the recorded net deferred fee amounts. Because letters of credit are generally not assignable by either the Company or the borrower, they only have value to the Company and the borrower. In determining the fair value of the swap guarantees, the Company assesses the underlying credit risk exposure for each borrower in a paying position to the third-party financial institution. Accrued interest payable The carrying amounts of interest payable approximate fair value. Other liabilities Other liabilities include the fair value of interest rate products, derivatives on the residential mortgage held for sale loan pipeline, foreign exchange forward contracts, risk participation agreements, and derivative related to the sale of certain Visa Class B common shares (see discussion in “Fair Value of Financial Assets and Liabilities” section above).
